Structural glass roof in Corby: what to know
Overhead glass in a glass roof is generally specified with a laminated inner pane. If the inner glass breaks, the interlayer holds the fragments together instead of letting them fall into the room. BS 5516-2 is the British Standard code of practice for sloping and overhead glazing.
Fixed frameless rooflights sit on a flat roof upstand with the glass edge overhanging the kerb, so from inside you see only sky and plaster. The upstand must be level, insulated and weathered into the roof covering, and the roof needs a fall so water drains off the glass.
Glass roofs need regular cleaning from safe access, never by standing on non-walk-on glass. Silicone joints between panes should be inspected for splits, gutters and outlets kept clear, and any chips or scratches on walk-on panels checked, because the top layer is designed to protect the layers below.
A new glass roof or walk-on panel is building work that normally needs building regulations approval through building control, covering structure, energy performance and, close to a boundary, fire performance. Planning permission may also be needed depending on the extension and the property, so check with the council.
What a typical job includes
- Lifting, positioning and fixing of every glass unit
- Coordination with engineers or builders where required
- Written guarantee terms and manufacturer documentation

- NN17, NN18 and the surrounding area, including Uppingham, Kettering and Market Harborough
- Coast
- Corby is well inland, around 66 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Corby the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.4 hours of daylight, rising to about 61° and 16.6 hours in midsummer. Overhead glass admits far more daylight than vertical glazing, especially in summer when the sun is high. South-facing glass roofs usually need solar-control coatings or fritting, while north-facing roofs can use clearer low-E glass to maximise winter light.
- Access and setting
- City glass roofs often need cranes or lifting robots, so road or pavement licences, parking suspensions and access over neighbouring property may be needed. Side returns usually sit on a boundary, so fire performance and neighbour matters should be checked early.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Options to choose between
Solar-control coatings
Coatings or fritted patterns that reduce heat gain and glare under overhead glass on sunny elevations.
Side-return glass roof
Large glass units spanning from the house wall to the boundary, supported on glass beams or slim steel, for extended kitchens.
Fixed frameless rooflight
A flat glass unit bonded to a minimal edge frame on an upstand, giving an unbroken view of the sky from inside.
Glass Roofs in Corby: questions
How much does a glass roof cost?
The cost of a glass roof depends on the area of glass, the size of each unit, the glass make-up and coatings, the support beams or framing, the structural design and the access for lifting. Walk-on and very large panes cost more because of their thickness. See the guide prices for typical ranges; the written quote fixes the price.
Does a glass roof need building regulations approval?
Yes. A new glass roof, frameless rooflight or walk-on panel is building work that normally needs approval through building control, covering structure, energy performance and fire performance near a boundary. Highly glazed extensions often need energy calculations to show compliance. The rules differ between England, Wales, Scotland and Northern Ireland, and we explain the route for your project.
Do I need planning permission for a glass roof extension?
It depends on the extension and the property. Some single-storey extensions on houses fall under permitted development, while others need planning permission. Flats, listed buildings and homes in conservation areas or under Article 4 directions have additional controls. Check with your council or an architect early, before the glass is ordered.
What guarantee comes with a glass roof?
Manufacturer guarantees apply to the glass units, coatings and any framing or fixings, and the terms are confirmed in writing. Supports built by others are covered by their own builder's terms. Guarantee terms for our installation are set out in writing with your quote, so you know what is covered and who is responsible before work begins.
